These coasters look lovely. Since you can’t see them in the store I was worried that they might look too cheap or be too thin or have imperfections that would affect their functionality. These exceeded my expectations. I ordered an eight of these and they are all beautiful and unique. Upon opening the box the first thing I noticed is these are nice and heavy and not at all too thin. These were a gift so I also checked to make sure none were cracked or lopsided and they were all functional in addition to their beauty. Since gifting these I’ve set a drink on them while visiting the recipients of the gift and they don’t have the issue where the coaster sticks the bottom of the glass when you pick it up. Basically, these are perfectly functional coasters that are also a beautiful piece of natural artwork and are high quality.
